        Web Inspector: serialize edge counts instead of indexes in heap snapshot
        https://bugs.webkit.org/show_bug.cgi?id=88324

        The serialized node structure currently holds an index
        of its first containment edge in the edges array.
        The index can be quite big (up to 7 digits for large snapshots).
        The patch changes the serialization format to pass
        node containment edge count instead. For most nodes the count
        is just a single digit number.
        This reduces serialized snapshot size and therefore its transfer time.

        [perf-test] Add a benchmark for querySelector()
        https://bugs.webkit.org/show_bug.cgi?id=87742

        Reviewed by Ryosuke Niwa.

        Now I am optimizing querySelector() (bug 87625).
        This patch adds a performance test for querySelector().
        query-selector-first.html queries an element that appears
        at the head of the document. On the other hand,
        query-selector-last.html queries an element that appears
        at the tail of the document.

        [perf-test] Add a binding benchmark for getElementById()
        https://bugs.webkit.org/show_bug.cgi?id=86808

        Reviewed by Ryosuke Niwa.

        Currently Bindings/dom-attributes.html is just a collection
        of random DOM attributes and methods. We should remove it and
        instead add more reasonable micro benchmarks by classifying
        DOM binding call paths.

        This patch adds a benchmark for document.getElementById(),
        which covers other DOM methods that return a Node Object.

        The reason why we want to add a benchmark for document.getElementById()
        in spite of the fact that Dromaeo/dom-query.html is already testing
        document.getElementById(), is that Dromaeo/dom-query.html outputs one
        result for several benchmarks (i.e. getElementById().nodeType,
        getElementsByTagName()[0].nodeType etc), and thus we cannot observe
        regression of getElementById() itself. (Catching regression of
        getElementById() would be critical.)

        Use runPerSecond instead of run to measure results in function calls per second (run/s) instead of time (ms).
        This allows us to continue measuring performance reliably even when WebKit's performance improves and results
        become too small for Date.now()'s precision (around 15 ms).

        It should also reduce perf. bots cycle time for slower tests because we limit the number of function calls by time.

        performance tests should be able to measure runs/sec rather than time
        https://bugs.webkit.org/show_bug.cgi?id=86021

        Reviewed by Ojan Vafai.

        Add PerfTestRunner.runPerSecond. It uses _runLoop but replaces _runner by _perSecondRunner
        to compute runs/s of runFunction.

        When _perSecondRunner is called for the first time, i.e. _completedRuns is 0 (notice this is -1
        in regular run/_runner), it slowly increases the number of function calls to runFunction between
        time measurements in order to discount the time used by new Date() calls themselves until the
        total time spent reaches 100 milliseconds.

        By default, runPerSecond runs the test for at least 750 milliseconds in each run, and executes
        21 runs, yielding the total run time of roughly 18 seconds. This is significantly faster than
        most of existing performance tests. Also see http://ejohn.org/blog/accuracy-of-javascript-time/.

        Finally, refactored the existing methods of PerfTestRunner to allow "runs/s" unit and share code.

        Update our copy of the HTML5 spec used for performance testing to match the latest version
        https://bugs.webkit.org/show_bug.cgi?id=69364

        Unreviewed.  The patch is too large to post, so landing this unreviewed. :(

        The copy of the html5 spec we were using for testing was over a year old
        and didn't have any of the subresources with it (we were only using it
        as an HTML parsing benchmark).  I'm about to use it for testing
        the full load/render time of the benchmark, so I've updated to the latest
        version of the spec (now 8mb instead of 5mb) and inlined two of the
        CSS files.  (Inlining the CSS was necessary to make my testing consistent
        as there seems to be a race with some timer fired after CSS load.)

        Increasing from 5mb to 8mb showed a similar 30% slowdown in our parser
        benchmarks as expected.

        This was designed to be a test for https://bugs.webkit.org/show_bug.cgi?id=68944

        PerformanceTests/Parser/html-parser is only testing parsing of the head element
        https://bugs.webkit.org/show_bug.cgi?id=69283

        Reviewed by Adam Barth.

        While investigating https://bugs.webkit.org/show_bug.cgi?id=68944
        I found that the html-parser benchmark was only parsing up to the
        first script tag per loop!  We've fixed this by adding the sandbox
        tag which will deny all external loads and allow the parser to
        synchronously continue parsing the entire document to completion
        (as we had expected it was doing).

        This changes the profile somewhat.  Line number counting is much
        hotter, since we're actually accounting for the parse of the entire
        document in our sample.

        Total sample time only about doubles, from 1800ms to 3800ms on my machine
        which is less than I would have expected.
